Abstract

一种诸如卫生纸之类的吸收性纸制品无芯纸卷(10)被设计成比以往所知的无芯纸卷更容易安装在旋转配送器(32)上。这种无芯纸卷包括一个吸收性纸制品(12)的卷筒，它是纸制品绕转轴(16)旋转形成的一个圆柱体，具有第一和第二平面端(14)，并且在无芯纸卷中有一对凹槽。第一个凹槽在纸卷的一侧(20)上并基本上相对于纸卷的转轴(16)同轴，第二个凹槽在纸卷的相对的第二侧面(22)上并也基本上相对于纸卷的转轴(16)同轴。文中也对无芯纸卷的制造和使用方法进行了描述。

Description

带有凹槽的无芯纸卷及其制造和使用方法
                        发明背景
1.发明领域
本发明适用于商用和民用的吸收性纸制品领域，其中吸收性纸制品包括卫生纸和纸巾。更确切地说，本发明涉及了一种吸收性纸制品的改进型无芯纸卷，这种纸卷可以很容易地装在配送器上。
2.现有技术说明
象卫生纸和纸巾一类的商用和民用吸收性纸制品通常是以纸卷的形式配给和发放的，差不多都有一个圆柱形的纸芯，纸制品就卷绕在其上。纸芯一般用某种纸板制成，纸板粘成一体并与纸制品粘在一起，以使纸芯保持完整而且纸制品不与纸芯分离。这样将纸卷装在转轴上以后就可分发纸制品了，就象在普通的浴室卫生间中的纸卷配送器一样，转轴通过或是穿透纸芯的内部。一些配送器包括轴柱，它们只插入纸芯中的空间一段有限的长度，分别如Lane和Simmons的美国专利390,084和2,905,404中说明的那样。
近来，卫生纸的无芯纸卷出现在市场上，主要是在欧洲市场上，它整个由纸制品绕成。这种无芯纸卷有利也有弊。从生态的角度来看无芯纸卷要优于有芯纸卷，因为无芯纸卷在生产过程中没有使用粘接剂或产生废弃物。另外，可在原先由纸芯所占的空间中装上更多的纸制品。有芯纸卷的造价要高于无芯纸卷，因为有芯纸卷有生产纸芯并将纸芯粘在纸制品上的费用。另外，无芯纸卷有在商业场所不易被偷的优点，因为它们与传统的配送器存在固有的不相容性。
另一方面，无芯纸卷的配送问题迄今为止还难以克服。使用无芯纸卷的传统型配送器通常包括一个封闭支撑表面，纸卷当转动时就支撑在其上；还包括一个开口，纸制品从这个开口通过。当使用时，这些配送器有一些不尽人意之处，包括不能控制抽出纸制品的拉曳阻力，实际上纸制品触及到配送器的内部，有些用户认为这是不卫生的，还不能在180度范围内向用户提供纸制品。
如果存在一种配送器，可装入一个绕其轴转动的无芯纸卷，就象有芯纸卷配送器那样，那么许多上述的问题就可被克服了。遗憾的是，这样一种配送器还未成功地开发出来。阻碍这种配送器的开发的一个问题是如何将无芯纸卷同轴地装在配送器上。如果纸卷不同轴，当纸卷旋转时就会出现转动不平衡。而且，如果纸卷的转轴没有精确地与配送器同轴的话，纸卷直至其报废都不能送出纸来，然而，因为典型的无芯纸卷具有平的，连续不断的侧面，这就很难确定它的转轴位置。
很显然，需要一种改进的装置、方法和产品，用来有效地分发吸收性商用和民用纸制品的无芯纸卷。
                         发明概述
因此，本发明的一个目的是提供一种改进的装置、方法和产品，用来有效地分发吸收性商用和民用纸制品的无芯纸卷。
根据本发明的第一方面，一种制作吸收性纸制品无芯纸卷的方法，为使用户更容易地使无芯纸卷的转轴相对于配送器同轴，包括以下步骤：(a)将一工具放在无芯纸卷的至少一侧附近，使工具基本上相对于纸卷的转轴同轴；(b)将工具压入纸卷的侧面中，在纸卷的侧面上形成一个可见的凹槽，它相对于纸卷的转轴同轴，从而维护人员可以更简单地使纸卷相对于配送器同轴。
根据本发明的第二方面，用于将吸收性纸制品无芯纸卷装入配送器的一种方法，包括以下步骤：(a)在无芯纸卷的至少一个侧面上找到至少一个凹槽；(b)利用凹槽将无芯纸卷对准配送器；(c)在对准位置将无芯纸卷固定在配送器上。
根据本发明的第三方面，一种比迄今所知的无芯纸卷更容易地装在旋转配送器上的吸收性纸制品的无芯纸卷，它包括一个吸收性纸制品的卷筒，它是绕转轴做成，形成一个具有第一和第二平面端的圆柱体；还包括一个至少在一个上述平面端上的凹槽，用来引导用户将所述卷筒相对于配送器同轴，从而无芯纸卷可被方便而又准确地装在配送器中。
本发明中所特有的新产品的这些及各种其它优点和特征在文中附带的权利要求书中有详述，并且成为文中一部分。然而，为了更好地理解本发明，它的优点及使用时达到的目的，应当参考附图和附带说明，图例构成了本文的另一部分，而附带说明中则列举和描述了本发明的优选实施方案。
                         附图简述
图1是一种传统型吸收性纸制品无芯纸卷的透视图；
图2A是描述本发明优选实施方案操作过程中第一步的示意图；
图2B是描述图2A所示过程中第二步的示意图；
图2C是描述图2A和图2B所示进程中第三步的示意图；
图2D是描述图2A至2C所示过程中第四步的示意图；
图3是描述将根据本发明优选实施方案制作的改进型无芯纸卷装到配送器上的装配图。
                     优选实施方案详述
现在参看图例，图中相同的参考数字代表对应的结构，图1描述的是吸收性纸制品12做成的传统型无芯纸卷10。无芯纸卷10绕转轴16对称，并且有一对相对的平侧面14，它们基本上是平的并且连续，如图1所示。正如参照图1后所想到的，很难将转轴16定位，它导致难以将上述无芯纸卷10装在旋转式配送器上，例如象图3中所描述的那种配送器。
图2A至2D描述了一种根据本发明优选实施方案的方法，制作这样一种吸收性纸制品12绕成的无芯纸卷10，让用户更简单地使无芯纸卷10的转轴16相对于如图3中所描述的配送器32那样的配送器同轴。参看图2A至2D，优选的方法是通过先将无芯纸卷10两个相对侧面20，22的选定部分润湿来实现的。在优选实施方案中，这是通过分别把一对喷嘴18伸向侧面22，把侧面20，22的中心区域润湿来做到的。然后将喷嘴18拉回，如图2A中表示的那样。
另外，也可用别的方法来实现图2A中所描述的润湿过程，如采用压槽工具本身来实现润湿进程。压槽工具上可有一流体通道，或有一个用于盛润湿流体的容器。
如图2B中所示，一对圆柱形的工具24，26伸向无芯纸卷10侧面20，22的中心润湿部分。工具24，26的直径最好是在大约1/32英寸到1/2英寸的范围内。最优选的是，工具24、26的直径大约为5/32英寸，当工具24，26伸入无芯纸卷10的湿润侧面20，22中时，最好绕各自的轴旋转，如图2C所示。发明人发现，通过把要刻凹槽的区域润湿可以使得做出凹槽所需的力小得多。同时，当形成凹槽时，润湿可以得到更均匀和平整的外形。另外，发明人认为做凹槽的最有效方法似乎是把旋转和伸入两个动作结合起来。一个活塞式的插入动作，没有旋转运动，特别是没有润湿过程，会破坏孔或凹槽的边缘，使之不容易得到均匀平整的外形。
在图2C中所示的步骤之后，撤回工具24、26，从而得到图2D和3中描述的吸收性纸制品的完整改进型无芯纸卷28。如图3所示，无芯纸卷28在其各个侧平面20和22上形成了清晰的凹槽30。
本发明还包括一种将吸收性纸制品的改进型无芯纸卷28安装在如图3中所示的配送器32上的方法，配送器是装在墙34上的。这一方法是通过先找到改进型无芯纸卷28的各个侧面上形成的凹槽30，再将无芯纸卷28对准配送器32来完成的。在实际中，这是通过将凹槽30对准配送器32中的定位销36，38来完成的。定位销36，38上具有销轴40，42，这些销轴从端部延伸，在操作中用来进一步将无芯纸卷28固定到配送器32上。一个复位装置44用于拉回第二定位销38，使得能更容易地向配送器32上安装无芯纸卷28和/或从其上将无芯纸卷28取下。
然而应当理解，尽管对本发明的很多特征和优点，连同本发明结构和功能的细节在上文中进行了描述，但公开内容只是说明性的，可在细节上做一些改动，特别是对于从本发明的原理到一些术语的广义程度范围内部件的形状、尺寸和安装来说，这些术语是在附属权利要求中表示的。
